Suffocation is a general term to indicate that form of asphyxia, which is caused by deprivation of oxygen, either due to lack of oxygen in the environment or from obstruction of the air-passages.
Fainting, also called syncope, is a loss of consciousness that is typically due to a lack of normal blood flow to the brain. Fainting is uncommon in dogs and not always caused by a lack of blood flow; there are other similar medical causes that result in fainting for both humans and animals. That said, no matter how scared dogs or cats may get, they never faint from fright the way a human might (e.g., from panic attacks, hyperventilating, etc.).
